The front door is an element that protects the room from prying eyes and uninvited guests. As a rule, a door is acquired for many years. For this reason, it must meet many criteria at the same time. First of all, the door structure should reliably isolate the room to be closed noise and heat. Strength and durability are its inherent properties, as this significantly affects the degree of safety. Of course, the door must also meet aesthetic requirements. Consider how modern doors differ from each other and how to make a choice without falling into an unreliable option.

Unfortunately, a door that cannot be cracked does not exist. Sometimes, even banking specimens with ultra-high strength are hacked. But do not be upset, because a high degree of protection is not only able to withstand an unprofessional cracker, but once again completely discourages attackers from contacting her.

Materials
The basis for the front door is most often metal or wood. It is worth noting that the latter is distinguished by its weak level of endurance, which forces owners to give their preference in favor of metal. The most common types of it in the manufacture of doors are stainless steel. It is not exposed to moisture and corrosion, which makes it durable.

A more budgetary alternative is considered to be steel processed by cold or hot rolling. The hot-worked version is cheaper, but such metal is poorly resistant to corrosion.

An important indicator in metal doors is their thickness, which affects the strength of the product. If the thickness of the metal does not reach 1 mm, then such a door is not recommended to be installed as an entrance door. In extreme cases, it can be used for outbuildings or technical premises. In order for the housing to be securely closed, it is recommended to choose doors whose thickness starts from 1.5 mm.

Design
The strength of installed doors is determined not only by the material. It is very important that the frame to which it is attached has a robust design. The absence or insufficient number of reinforcing stiffeners will allow opening the door with little effort. The best option is the one where a mixed system of ribs is used, assuming their horizontal and vertical arrangement.

Choosing the front door for your apartment or house, you should not focus only on its external qualities. It is important to remember that a strong and reliable door is a guarantee of the safety of property from intruders.
